Look man, I believe I was more than polite and respectful when I asked you not question the man's expertise and workmanship... Let's just keep this on a technical level, it's much more rewarding for everyone here. We are after all, all here because we're enthusiasts.
You are right though, I have never built any parts, let alone an exhaust system.

Otherwise I think I've contributed more technical info in this thread than most others for no other reason than wanting to help.
Anyway, best of luck (really).

No offense, Mild steel should NEVER be used on a Mercedes... period. Some may view that as an opinion and may risk it anyways. Just because it CAN be done, does not mean it SHOULD be done. But honestly, if you are spending that much on a Mercedes in the first place, only the top quality components should be installed. Mild Steel will always rust no matter how you try to stop rust from forming... it always does b/c rust never sleeps.
A high quality set of stainless steel headers as mentioned above will last the life of the vehicle and you never have to worry about them again. That is why we only produce SS headers b/c its what these cars deserve, anything less would be trying to "cut corners", and that shouldn't be done on Mercedes.
With that said, lets not let this thread turn sour, keep it on discussion and avoid the quarreling if possible as it is a good thread with good info.

Well you won't pass emissions in CA by virtue of the design of a LT and you'll fail the visual inspection as well.
Otherwise, no you don't need them, you'll make more power and run cooler w/out them. On the downside it will be significantly louder and you may notice the smell of unburnt gas while driving-=kind of sucks on a date. There will be decent gains from going catless (even if only at the track) even with a PD blower.

Any ballpark on savings by using no cats and my own x-pipe and mufflers?

With all due respect, why pay $6K for what is looking more like $3K? Getting 10 cars is **** for me. I've always been able to round up group buyers just not yet. Also, we need to think of our 63 brothers as well. Maybe you can get me a group buy where I can mix and match 55k and 63 cars?

and if i was so snobbish to say that mild steel isn't good enough for a mercedes, i'd probably be too snobbish to want anything but inconel anyways.

Inconel would only be useful in a high boost turbo app. 304T can take blowers all day long, 314 would be overkill, Inconel = working with an insanely difficult (and extra heavy) to work with material ($$$$) for no benefit whatsoever in this case.

You really want to do it right? Only Titanium will do. Every time you run the car the exhaust will get stronger, just make sure that you leave clearances since Ti tends to grow with heat

You're going to need to tune this system. Without flowing the head the chances of hitting the Primary/Secondary/Collector combo on the first shot is ZERO. Hell do the collector wrong and you'll take a 25hp hit Easily. That means that your going to have to try it a few times. Since that's the case you would be STUPID to build the system out of anything BUT cheap mild steel.Then when you get it right you build it out stainless or titanium. ONLY then not before.

Better tell just about every pro race team and every aerospace manufacture on the planet to use something better. Those two industries are the land of Unobtanium, they can use anything yet they use Ti....

Let's see I know a few of the top NASCAR engine guys, Most of the ALMS/IMSA/SCCA Pro guys and they don't claim one thing and then run another. Hell a simple Ring test and pocket magnet will tell me what the exhaust is made of.

Now you've made the claim, time for you to show your cards.

Experience has nothing on second hand knowledge and researching on the net.

yes, but i didn't want to start a flame war against you again. how do you get your knowledge...oh i forgot, you were born with it. 
and for someone who's never actually tuned an ecu, you sure seem to talk a lot about doing it. i'd suggest you don't go pointing fingers andy.

I've tuned everything from Ford GTs/GT500s, all makes SRT8, Vipers, to Z06s/Vettes. Basically everything domestic. The Euro stuff is new to me I admit, but I've got the best teacher in the world. So as far as tuning or anything else goes, I don't just "talk".
